Hi I have got a GTR R34 and I have got a knocking sound front/rear suspension, noise sounds just like the shock mounts are loose but I have checked them and they are fine, I have also checked the suspension arm bushes and doesn't seem to be any play there, only get the noise when the road is a little rough, it is not there on the smooth road.

Does anyone have any ideas, I seem to think the ball joints on the outer bearing carrier for the axles have got play in them???? I am going to replace them anyway the front has got a large one on top and a smaller one bottom and the rear has got one on the bottom where can i get these...

Hopefully sort it out giving me the sh....ts. Just had the car of the road for 9 months gettingnew engine,PPG gearbox,brakes now want to sort this.

Cheers Dave.

It must be damn hot working up there in Cairns David!

Can you take your car to get an 'efficient but cheap' 24 or 50 point check with either Pedders or Jax?

Then you can act on the report yourself.

My 1st cousin, also a David is a head mechanic at Cairns Toyota. I believe he's a good diagnostician if required. He knows me as Terry, not Tez

Hope this helps.

let me know how you go with this, i have some interesting noises that ALWAYS disappear whenver i drive near my suspension place, so damn annoying!

mine are 99% from the rear only though. They have also checked once to make sure everything is tight.

Does your happen whilst turning or just going straight over bumpy roads?

Thanks for the reply's from everyone, no its not the coil overs they are Ohlins Flag R the best you can get brand new when I did the engine, only happens when Im going over a potholed road or a rough road, more noticeable at low speed because of less road noise in the car.

Will have to take it in but dont want some dickhead working on it......

How stiff have you got the damper settings?

Hello Bakes,

I have got them set at mid setting, is not coming from the shocks but the rear noise is associated with wheel travel, Im pretty sure it is the ball joint the rear bottom arm is mounted on.

OK, good luck with getting it all sorted. Try and take it to a specialist place that work on GTR's etc. Id avoid the mainstrem places

Think I have found the problem there is excessive play in the Hicas rod ends, the ball joints closest to the rack. I will have to source new ones..

      R32 gtst speedo out by 10kph

      By -Jimmy- · Posted

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .
